Reproductive Technologies: An issue for our time
Thursday, 13th March. 1:30 pm – 2:30 pm
In 2012 there were 60,860 children born in New Zealand. Each child was the result of successful conception, pregnancy and birth. However conception and pregnancy are not always straightforward.
- Many conceptions do not result in live births – around 15% of confirmed pregnancies result in miscarriage.
- A further group of conceptions result in live births that bring challenges for the parents and the child associated with potential or actual health issues.
- Additionally we are having fewer children and mothers are older.
The chart below from Statistics New Zealand shows that New Zealand women have 2 children on average. However in the 1960’s the average was 4 children.
Assisted Reproductive Technologies
In vitro fertilisation (IVF) is a reproductive technology that enables a follicle to be collected from a woman and fertilised in vitro, before re-implanting into the womb. This technology has enabled many couples who otherwise would not be able to have children, to have a child. Preimplantation Genetic Diagnostics (PGD) is a further technology that allows embryos created via IVF, to be screened prior to re-implanting in the womb. It is used to enable couples at risk of producing embryos with genetic abnormalities the opportunity to have their embryos checked for specific conditions before a pregnancy is established.
In 1978 Louise Brown became the first baby born following in vitro fertilisation (IVF) treatment. Since then more than 5 million children around the world have been born as a result of successful IVF.
In New Zealand, the first IVF baby, Amelia Bell, was born in 1984. The New Zealand based IVF-l’ings web site tells Amelia’s story, and explores the research from around the world in the field of assisted reproductive technologies. Professor Winston was a pioneer in this field. In New Zealand scientists from Gravida, the Liggins Institute and Fertility Associates are actively working in this area of research.

In the last 35 years, advances in reproductive technologies have provided opportunities for couples to overcome a range of different barriers to reproduction and have a baby. However, these technologies raise a number of ethical and social challenges such as:
- Who should have access to this technology?
- Is it ethical to select embryos for specific conditions?
- What happens to unused embryos?
- When is it acceptable to use these technologies?
- Which genetic conditions should we select for or against?
- Who should pay for such technologies?
- How does this technology sit with differing cultural and religious beliefs?
- Who should decide on regulations around the use and development of reproductive technologies?
- What are possible future developments in this area?
